But they are not in same table, are  they? I mean if you select on base table, 
how do you expect primary key constraint to be held against n child tables?

I dunno what standard says about this. But as long as, select from child table 
on primary key  does not return duplicate row, I wouldn't worry.

This can be a really annoying issue for somebody. But I would advice him/her 
to work on table design rather than proposing it as a defect in PG.
